MARBLEIZING PROCESS.

Application led January 24, 1927, Serial No. 163,200. Renewed 'March This invention is concerned with processes for refinishing the surfaces of materials 1n imitation of the natural appearance of other dissimilar materials and has for its general object the provision of a novel process for the reproduction of a marble appearance on the surfaces of materials other than marble.

More specifically my invention has for its object the provision of a` process for repro- 1 ducing in natural colors a marble appearance on surfaces of materials other than marble.

Other objects of my invention will hereinafter be set forth in the following description of a preferred manner of fulfilling the steps 0f my process. The essential characteristics are summarized in the claims.

In the drawings, in Fig. 1, I show a crosssection of a piece of material, the surface of which has been treated to resemble the surface of a marble slab after the manner of my process; and Fig. 2 is a graphic representation of the application of several coatings of pigments to a surface to impart to the surface a marble appearance. i t* My invention contemplates the use lof the photographic method of obtaining a metallic etching through a carbon resist and thereafter the etched plate or roll, as the case may be, has applied colors to simulate thenatural colors of a marble surfacev to be imitated. These colors are successively applied to the etched plate or roll and partake therefrom, the marble pattern in natural contour or outline. This is accomplished by the use of a transfer roll and the transfers applied to the surface being treated in a certain color order whereby the applied coatings when brought into A superimposed contrast simulate the natural marble surface. y

I first obtain a photographic reproduction of the marble surface on either -the usual photographic plate or film and from the plate or film I produce a carbon resist, preferably 5 using a screen and the carbon resist thus obtained, is used in a well own manner to reproduce either a zinc etching or electrotype prepared therefrom andhaving the characteristics of the well known half-tone plate or a photogravure plate or roll.

the latter. If it is desired to use a photogravure plate or roll, one step'in the photogravure process is omitted, namely, the making` of a positive film or plate from the photo- @ii graphic plate or ilm. is produces aphosurplus pigment thereto pigments of different but apply this I prefer to use CORPORATION OF MICHIGAN'.y

togravure roll or plate which is in reality the reverse of the usual photogravure roll or plate. When the plate is 'thus properly etched, it is then ready for use. Iv first treat the surface which is to be marbleized vwith a ground color A simulating in shade as nearly as possible, the natural shades or tones'to be found in the grain or cleavage marks of the natural marble which is to be imitated. I then apply to the photogravure plate or roll a pigment or ink resembling in turn as nearly as possible another color to be found in the original marble slab in the grain or cleavage marks thereof. After using a doctor blade to remove the and thereby leaving pigment deposited only in the etched interstices thereof. I remove the pattern thus outlined by the plate with a transfer roll and apply this pattern designated by the reference character B in the drawings, over the first ground coat previously applied to material to be treated by rolling the transfer roll thereover.

I then apply, after the coating which has been applied in the form of a transfer, has had sufficient time to dry, to the photogravure roll or plate a pigment of still another color resembling in tone the general or dominating color tone of themarble slab to beimitated or reproduced and after using the doctor blade to remove the surplus pigment, I transfer a second pattern in this different color from the plate to the surface being treated, second pattern designated as and which in outline is the same as the first pattern B previously applied, to the surface but out of registration with the contour of the first pattern B. The second application produces an unusual result, in that portions of the ground color and the second color will show through the last applied color at the grain or cleavage veins of the pattern and Where the variouscolors are superimposed there is a variation in tonal effect simulating to a striking degree the varying but natural colors of the original marble slab.

Referring again to Fig. 2 it will be noted that when the two transfers overlay as at D the tone is deepened but this depth of tone will vary in accordance with the variation inthe tones of the `respective transfers, each of which may vary throughout its surface; and also there will be variations from the initial pigment-color of the respective trans- REISSUEB IUD lill

v fers for example at E and E in accordance with the degree of showing of the color of the ground coating A through the transfers. The graphic representation shown in Fig. 2 however, is considerably exaggerated in that only small areas of ground color will be unobscured in the actual reproductions. A protective transparent coating F of varnish or lacquer -may be applied to impart to the treated surface the glossy appearance of polished marble.

This process, as will be readily understood, can be` usedd for the application of more than two Acolors which will show at places on the surface unblended, while at other places where the pattern contours completely superimpose the composite colorwill vary in tonal vdept This result can be obtained as sug gested by either the use of a photogravure half .tone or electrotype printing surface derived through the use of the process of producing printing surfaces by photographic methods.

I claim: 1. A process for decorating surfaces which includes the use of an etched plate or roll made from a photographic resist, by treating the surface to be decorated with an underlying or ground coating of pigment, applying the pigment to the etched plate or e roll of a color simulating one of the natural grain colors of the marble, transferring the pigment from the Aplate or roll tothe surface to be finished, drying said transferred pattern, applying to the etched plate or roll a l second'pi ment coating and removing saidY coatingit erefromby a lresilient rolland thereafter Ysuperimpos'ingthe `transfer pattern over then previously .transferred pattern but out of register therewith.

y2A process for'` simulating marble `surfaces on the surfaces of materials other than marble comprising etching ak photogravure plate or roll-b using af photographicnegative'plate or fi m obtain?, by photographing a marble slab forming a carbon resist from the photographic negative, then using the positive carbon resist thus formed to form a photogravure plate or roll whereby the plate or roll thus formed may be utilizable to form igment transfers of more than one color to applicable in superposed application relaion.

3. A process of reproducing a marble appearance on a hard surface comprising using an etched printing surface prepared from a positive carbon resist of the marble surface to be simulated by app-lying pigment to the etched surface, removin the pigment from the etched'surface by t e use of a resilient roll, transferring the reproduced pattern on the resilient roll to the surface to befinished, drying said transferred pattern, applying a different colored pigment to the etched pattern, removing the pigment from the etched first' pattern by the use'of the resilient roll, and superimposing this attern of a different colored pigment over-the previously transferred pattern whereby marbleizing contrast is effected on the surface to be decorated.

4. A process of reproducing a marble appearance on a hardsurface comprising using an etched printing surface prepared from a positive carbon resist of the marble surface to be simulated by applying pigment to the etched surface, removing the pigment from the etched surface by the use of a resilient roll, applying a light shade ground coat to the surface to be finished, transferring the reproduced pattern on the resilient roll to the light shade surface, applying a different colored pigment to the etched pattern, removing the pigment from the etched pattern by the use of the resilient roll, and superimposing this pattern of the different colored pigment over the previously transferred pattern.

5. A process of reproducing amarble appearance on a hard surface comprising using an etched printing surface prepared from a positive carbon resist of the marble to be simulated by using the etched plate or roll thus formed to make igment transfers of more than one color and) separately applying the transfers to the surface to be finished with the transfers of varying colors out of register. y
